Tropical Depression EIGHTEEN-E Forecast Discussion

The area of low pressure (91E) that NHC has been monitoring has now 
become a tropical depression well offshore of southern Mexico.  
Satellite images show that deep convection has been increasing and 
consolidating near the center, and ASCAT data from several hours ago 
indicated that the system had developed a well-defined center.  
Dvorak estimates from TAFB and SAB have increased to 2.5/35 kt, but 
the initial intensity is set a little lower at 30 kt since the ASCAT 
pass suggested that the Dvorak estimates have been running a little 
high. 

The depression is drifting northward at 2 kt.  A continued slow 
northward motion is expected during the next couple of days as the 
system moves in the light steering flow between a ridge to its 
northeast and a trough to its northwest.  Beyond a few days, the 
weakening system will likely turn westward in the low-level flow.  
However, by the end of the forecast period, there is quite a bit of 
spread in the track guidance making the long-term forecast somewhat 
uncertain.   The NHC track forecast is near the various consensus 
aids.

Some slight strengthening is possible during the next couple of days 
while the depression remains in generally conducive environmental 
conditions.  However, beyond that time, an increase in vertical wind 
shear should cause slow weakening, and most of the models show the 
system decoupling or dissipating by the end of the forecast period.  
The NHC intensity forecast lies near the middle of the guidance 
envelope.
